5 Claims. (Cl. 123-196) The invention is a device that may be attachedin an intake manifold 5. It will be noted that to the intake manifold ofinternal combustion enthis may be connnected in the same opening thatgines which admits lubricated air to the intake is provided for thewind-shield wiper and a fitting manifold and is controlled by theaccelerator so 6 may be provided on the nipple 4 so that the wiper 5that the air will be injected with the gasoline connection may be madethru a nipple '7 at the 60 and shut off as the gasoline is shut off.opposite side.

4 which may be screwed into a tapped opening It will be noted that theaccelerator rod 14 is '1 connected to the throttle valve of thecarburetor and this rod is in various positions for different types ofcarburetors and engines so that the connection between the valve 2 andthe accelerator rods and also the general construction of the entiredevice may be varied considerably for different types of engines. Theapparatus shown being only typical.

It will, therefore, be understood that changes may be made in theconstruction without departing from the spirit of the invention. One ofwhich changes may be in the use of other means for connecting the deviceto the intake manifold, another may be in the location of the point atwhich it is connected as it will be understood it may be located at anypoint in the manifold, another may be in the use of a valve of adifierent type, another may be in the use of other means for operatingthe valve, another may be in the use of other means for supplying thelubricant, and another may be in the use of other means for feeding thelubricant to the incoming air.

The construction will be readily understood from the foregoingdescription. In use the device may be provided and installed as shownand described and it will be noted that normally the valve 2 is in theclosed position and when the accelerator is moved to open the throttlevalve the valve 2 is also automatically opened and the valve will begradually opened so that only a small amount of the lubricated air willbe admitted first and as the throttle valve is opened wide a larger, orproportionate amount of the lubricated air will be admitted. It willalso be noted that as soon as the throttle valve is closed the valve 2is also closed so that there is no danger of stalling the engine byadmitting an over supply of air while the engine is idling.

Having thus fully described the invention what I claim as new and desireto secure by Letters Patcm, is:

1. A lubricated air injector comprising a tubular member adapted to beinstalled on the intake manifold of an internal combustion engine,a

valve in said member said tubular member directly connected to saidintake manifold and providthe atmosphere to the manifold, means ing freeair passage from the atmosphere thereto when the valve is in the openposition, means controlling said valve by the accelerator connectingrod, a lubricator storage chamber in connection with said tubularmember, and a wick extending from said storage chamber into said tubularmember.

2. An attachment for internal combustion engines having intake manifoldswith carburetors in combination therewith comprising a member attachedto the intake manifold providing a direct and free air passage from theatmosphere to the manifold, a valve in said passage, means operating thevalve with the carburetor operating means, a lubricant reservoirpositioned below said member, and a wick extending from said reservoirinto the path of air passing thru said member.

3. In an auxiliary air inlet device for the intake manifold of internalcombustion engines having a carburetor, said device providing a directand free air passage from the atmosphere to the intake manifold, alubricant reservoir in combination therewith, a wick extending from saidreservoir into said freeair passage, a valve in said device positionedbetween the lubricant reservoir and the intake manifold, and meansconnecting said valve to the carburetor operating means.

4. In a device as described in claim 3, bleeder openings in the valveproviding gradual opening thereof permitting a comparatively smallamount of air to enter themanifold when the engine is starting.

5. In an auxiliary air inlet device for the intake manifold of internalcombustion engines in which the manifold is provided with a carburetor,said device having a member connected to the intake manifold providingfree air passage from exposing a small amount of lubricant to the air inthe free air passage in order that the air may absorb some of thelubricant, and a valve in said member between the manifold and the pointat which the lubricant is exposed to the air,.- said valve operated withthe carburetor.
